Robust design

The materials of the pump ensure excellent corrosion resistance. The pump housing and impeller are made of high quality stainless steel. Furthermore, the mechanical shaft seal offers high-wear resistance and a long operating life.


Thermal overload protection

The single-phase version is effectively protected against any accidental overload, by built-in thermal protection. This means that no additional motor protection is required.


Handy and easily transportable

The carry handle mounted on the pump housing makes it handy and easily transportable.


Option for automatic operation

The pumps are available with float switches for automatic on/off operation.
